To all whom it may Concern;

Be it known that IfI-IueoPnTnasnn, a chemical engineerpand a subjeet of the German Emperor, and a r'esidentof 1-8LKaiser- Alle, in the cityjof Wilinersdorf, near Berlin,

Kingdom of Prussia, and German Empire,

have invented a certainnew and user'nlFillmg Material for Reaction-,Cl1ambers,' of

which the following is a specification.

This invention has for its ob'ect to provide a packii'ig orfilling material for reaction chambers, absorption chambers, gas puriliers and the like, constructed and adapted to be arranged in such manner that gases and liquids maybe brought into intimate contact eaclrwith the'other, so that eachwill permeate and be. caused totreact perfectly upon the other, i I

'The invention is intffnded to secure the highest degree of efficiency in theabsorption of vapors or gases by liquids, to cause the removal of solid impurities from gases or va-v pors, and to avoid the tionsby iluc dust andt 10 like. The packing material, forming the sub'ect of this invention, is composed ofperfor ted plates arranged in pairs at an angle, oroppositely inclined with relation to each other, the plates of each pair, being either separable or permanently connected to each other, and presenting a roof shaped structure, the top or meeting edges of theplates forming a substantiall y horizontalridge.

The oppositely-inclined plates are rovided with horizontal perforations, and tieir end faces are preferably so arranged as to permit the plates to stand inclined against the horizontal, and to be supported against each other. The plates of each pair may eitherbe detachable from eachothor or they may. be made in one piece, so as to constitute an integral roof-shaped structur Alarge number of such hppositely-incli rangedlsideb sir e 11 nectedfifdes: gated. structure made n pairs'of plates; lThe tegrally com right angles to said rig Lion is ietw fi rangement of perfo tio' tions ,erinit the liquid o go, though myinven:

v -ip,s,l down u-pon tic outer sides; to flowthi ough u'pon liquid from one surface to the other.

and at the-same time the gases are free to flow u on both surfaces. The inclination of the p ates compels the ascending gases to im-- pinge against the inner sides of the plates and to flow through the perforations and along the outer sides, thereby becoming intimately mixed with the liquid, which in its turn, rebounds from the outer inclined surfaces of the plates, and thereby becomes sprayed into atoms. An intimate reaction and mixture of said spray with the jets of gases emanating repeatedly su )divide and reunite the differ-' ent particles of the gases and liquid. The ascendim gases are reflected by the o positely-indlined surfaces of the adjacent pfittes to a large extent, and rebound from one surface against the op osite surface, so that the are compelled to flow several times throug the same space and to pass through the holes in the plates during the whirling motion imparted to them. By this means an intimate contact of the reagents is produced, and a large area of acting surface is provided. Any flue dust carried along withthe gases is either reflected on the inclined surfaces or-is compelled to slide down the inclines, so that deposits of flue dust which might interfere with the operation of the chambers filled with said There is therefore no liability of any injurious reduction of draft.

The airs of plates may be arranged at an. desirer distance from each other, so that 1t is possible to change the distance between the airs in several parts of the reaction chamier, without any liability of the upper rows dropping or breaking down, even when arrangm the said bodies at a considerable distance from each other. 'In case some liquid should collect at the lower edges of the dates, the then descending jet of liquid will be reflected, ,and converted into a spray by the plates just below. In order to further restrict the lit uid from collecting at the lower cdges oftlie plates, the said lower edges may be provided with downwardly directed The edges of the perforations of the plates are preferably rounded off, in order to facilitate the passage ofqtge 0 plates ma be provided with surfaces of the ike, for t e purpose of preilutings or the venting the coating of the surfaces with liquid, and in order to divide and reunite the current of liquid as many times as possible.

On the accompanying drawing one of the 5 preferred forms of construction of the packing material according to my invention is shown, Figure 1 being a front elevation, and Fig. 2 an end elevation.

n the drawings, a a represent the two oppositely inclined plates, which are so arranged relatively to each other as to form a root with a substantially horizontal ridge.

b I) represent the horizontal perforations of the plates.

f f represent the flutings on the surfaces of the plates.

d d represent the downwardly directed notches in the lower portions of the outer surfaces of the plates.

g g are notches in the upper portions of the outer surfaces of the plates.

-My improved packing bodies may be made of any length and they may be built up in parallel rows, preferably arranged so as to alternate with each other, or in rows crossing each other to form a grating, no special sup ports being required. There is no possibility of the gases or liquids flowing directly and unimpeded through the chamber, tower or the like, the liquid which runs down from any of the rows orlayers of packing material, being sure to be converted'into spray in the next succeeding lower layer. As compared with the usual Lunge plates, the new pack- 5 ing material presents the advantage of a fre uent change of direction of movement of t e geagents, of a uniform wettin of both surfaces of the plates, and of an increased duration of contact of the various reagents.

40 The plates are preferably iven such an inclination that the li uid wil trickle down in a uniform stream bot at the outside as well as at the inside of the plates.

. My improved packing material is distinguished from an 'ular packing material here tofore employe ed es or ridges are Vertically arranged, the sid es which meet to form said ridges being moreover not inclined so as to present a roofshaped structure. The said rior packing material, which, on account 0 the substantially rectangular inclination of its narrow end surfaces with relation to its front sides,-

could not be horizontally arranged, and was very deficient in stability, so that special supports, brackets, supporting rods or the like were required to secure them in place in the reaction chamber. Moreover the assemblage and building up of the said prior acking was difficult, and no abutting suraces or resistances from which the jets of liquid and of as or vapors could rebound and become isintegrated, were provided, the li uid and gas on the contrary flowing throng the reaction chamber in a substanin which the connecting seaeee tially vertical direction and without reacting sufiiciently upon each other.

As compared with the usual Lun e plates for filling reaction chambers, the fbllowing advantages are presented by the new filling bodies:

l. The manufacture of the new material is very easy and simple.

2. No special supports are necessary for packing the material, as the bodies of one row will constitute a perfectly stable support for the succeeding upper rows.

The entire packing is more stable than with other plates; the packing may be effected, so as to constitute a net shaped 3 structure. 7

4. The said bodies present more than double free sectional area than the plates.

5. For the same space of reaction chamher there is three times the acting surface, 35 the distance of the layers of plates in the usual plate tower of Lunge being taken to amount to about four inches only.

6. The liquid is retained in the chamber for a considerably longer time, inasmuch as the dripping down from a certain height, a drawback in the plate tower, is dispensed with. By this means the duration of the time of reaction of gases and liquid is prolonged.

7. The gas current does not ascend vertically, but it is always deflected sidewise, also resulting in a longer duration of the gas reaction.

8. In the Lunge plates most of the liquid 00 remains on the top side of the plates, that is to say, at the )oints where a minimum of gas can pass, while on the lower side, where the gas impinges with great force, there is the least amount of liquid. In the new 05 packing body, both parts are equally wetted.

9. In the Lunge plates the several jets of gas are directed parallelly u )ward, while in the new packing material t e gas jets are 10 directed against each other, resulting in a more thorough mixture and an increased mutual reaction.

The packing material described may of course also be employed for gas washin purposes, in themanufacture of alcohol and spirit and the like, and also for filling the c lambers employed for heating air and gases in the operation of gas producer plants.

I claim:

1. Packing material for reaction and absorption chambers, etc, comprising oppositely-inclined perforated plates which meet at their upper edges to form a substantially horizonta ridge.

2. Packing material for reaction and absorption chambers, etc. comprising two oppositely-inclined perforated side walls forming a roof-shaped body, the ridge at the mpacking 10 planes, the outer surfaces of the'walls having downwardly directed notches.

4. Packing material for reaction and absorption chambers, etc., comprising two oppositely-inclined perforated side walls'forming a roof-shaped body, the ridge at the ins tersection of said wallsand the base edges of l the walls being I in substantially parallel planes,-the outer surfaces of said walls being fluted;

5. Packing material for reaction and absorption chambers, etc., comprising oppositely-inclined perforated plates which meet at their u per edges to form a substantially horizonta ridge, the perforations and bases of the lates being horizontal whereby they meet t e inclined faces of the plates at other than right angles. v

6. Packing material for reaction and ab sorption chambers,-etc., consisting of plates united to form a roof-shaped structure having horizontal top ridges and provided with perforations which are horizontal when said structure is set in upright position for use.

In witness whereof I'have hereunto set my hand in presence of two Witnesses.
